I like your program very much, but one problem that still isn't solved drives me crazy.
I run Windows 7 on some of my PCs (both x86 and x64 versions), and if AHCI is enabled on them, it makes impossible using your software. E.g., I write this on the PC with Windows 7 Home Premium x64 and CD Burner XP v.220.127.116.115. It has ASUS P5K-VM mainboard (with Intel chipset, ICH9), and Optiarc DVD RW AD-7173S SATA drive. If I enable AHCI, your program says it doesn't see compatible drives. But at the same time, if I try to erase a disk, CD Burner XP does perfectly show me my drive(!). Firmware
